Really very interesting reading.

It seemed to me DirectX 12 is really revolutionary far beyond anything I ever seen, so far superior to Mantle.

AMD slide showed DirectX 12's undisclosured benchmark with AMD A10 7850K which have just 4 core performed an astounding 2,739,266 drawcalls at 1080p resolution. Cant imagine what DirectX 12 games will look like with millions drawcalls, my 3770K could push out 4,963,857 drawcalls when compared Passmark CPU Mark against AMD A10 7850K, 8C/16T 5960K could push 8,518,732 drawcalls.

Nvidia features is very interesting too, we already got MFAA but surprise there will be 2 new AA modes Nvidia not announced yet called polymerization G-Buffer anti-aliasing (Aggregate G-Buffer AA) AGAA and Cumulative anti-aliasing (Accumulative AA) CAAA. AGAA 2A technique delivers quality of 32X MSAA while having the performance penalty of 4X MSAA.

Wow I am so exciting cant wait to have DirectX 12 driver soon, AGAA seemed very cool feature so don't have a clue what CAAA does.

Spoiler

The same chart but showing different results.

Not that any of that matters to be honest, if there are only 100 gamers and you code your game in such a way that only 20 of them can play it, your an idiot, you code your game so that everyone can play it then your on to a winner.


Of course not to forget the fact that by the time these games that utilise DX12 get here all the non DX12 cards will be too slow to play them anyway.

It say Geforce 900 series is only cards supported full DirectX 12 feature level 12.1 with Conservative Rasterization and Rasterizer Ordered Views, GCN do not supported these features.

I found a link below from beyond3D confirmed with images from cap viewer showed GTX 980 supported it while 290X did not supported it.

Just found this GTC2015 Nvidia presentation talked about cool features ACAA, CGAA and FTIZB.

ACAA seemed a big improvement over MSAA with less memory bandwidth, CGAA 2A is amazing and wow FTIZB can render ray traced quality.
